Does anyone use different notification sound for different workspaces on Slack or is it just me 🤔

Could someone explain why React is called a library and not a framework, simply and concise :)

Our teacher has assigned us a project that should be well documented, well built, written in a language that he has no freaking idea how it works and the project should be Facebook rich with features, we are three members in a team and the project should be done in less than two months. How the hell should we deal with this freak?
